A swivel mechanism for a vehicle seat that includes a plurality of pairs of plates that are rotatively coupled providing a first stage of movement where the seat and at least one plate rotates while displacing out of the way of an obstacle and a second stage where the seat and at least one plate rotates without displacing. In an embodiment, a base plate that remains fixed in a home position while a coupling plate and seat-supporting plate rotate about a first pivot offset from the center of the base plate during the first stage and the seat-supporting plate rotates about a second pivot disposed in a center of the coupling plate during the second stage. The coupling plate is slidably coupled to the base plate and to the seat-supporting plate with at least one guide pin and slot arrangement limiting relative movement during the first and second stages.
